Every year, American high school students take SATs, which are standardized tests intended to measure literacy, numeracy, and writing skills. There are three sections - reading, math, and writing, each with a maximum score of 800 points. These tests are extremely important for students and colleges, as they play a pivotal role in the admissions process.

Analyzing the performance of schools is important for a variety of stakeholders, including policy and education professionals, researchers, government, and even parents considering which school their children should attend.

You have been provided with a dataset called schools.csv, which is previewed below.

You have been tasked with answering three key questions about New York City (NYC) public school SAT performance.

import pandas as pd

# Read the CSV file
schools = pd.read_csv("schools.csv")

# Filter schools with average_math at least 80% of 800
best_math_schools = schools[schools['average_math'] >= 0.8 * 800][['school_name', 'average_math']]

# Sort by average_math in descending order
best_math_schools = best_math_schools.sort_values(by='average_math', ascending=False)

# Calculate total_SAT for each school
schools['total_SAT'] = schools['average_math'] + schools['average_reading'] + schools['average_writing']

# Get the top 10 performing schools based on total_SAT
top_10_schools = schools[['school_name', 'total_SAT']].sort_values(by='total_SAT', ascending=False).head(10)

# Group by borough and calculate count, mean, and std of total_SAT
borough_stats = schools.groupby('borough')['total_SAT'].agg(['count', 'mean', 'std']).round(2)

# Find the borough with the largest standard deviation in total_SAT
largest_std_dev = borough_stats[borough_stats['std'] == borough_stats['std'].max()].reset_index()

# Rename columns
largest_std_dev = largest_std_dev.rename(columns={
    'borough': 'borough',
    'count': 'num_schools',
    'mean': 'average_SAT',
    'std': 'std_SAT'
})

print("Best Math Schools:")
print(best_math_schools)
print("\nTop 10 Performing Schools Based on Total SAT:")
print(top_10_schools)
print("\nBorough with the Largest Standard Deviation in Total SAT:")
print(largest_std_dev)
